PHILIPP J. BENDER, OF NEW YORK, N. Y.

IMPROVEMENT IN FANNING APPARATUS FOR ROOMS.

Specification forming part of Letters Patent No. 163,628, dated May 25,1875; application filed September 21, 1874.

To all lwhom it may concern:

Be it known that I, PHILIP? J. BENDER, of the city, county, and State ofNew York, have invented a certain new and usef'ul Improvement in Fansfor Rooms, of which the following is a specification:

This invention relates to a system of rotary fans, which are disposed ina room or apartment in such a manner as to keep the air of the room in acool state, and the room ventilated.

My invention consists of a joint having screw-threaded sockets, in whichthe screwthreaded shanks of the fans are screwed, the said fans beingcapable of adjustment, and being locked in position by locking-nuts orotherwise. This socket-joint is mounted upon a shaft arranged in ahanger, so as to be adjustable vertically upon said shaft, all as willbe hereinafter described, and pointed out in the claim.

This invention is illustrated in the accompanying drawing, in whichFigure l is a side view, as put up in a room or apartment. Fig. 2 is alongitudinal central section of the socket-joint on a larger scale thanin the preceding figure.

Similar letters indicate corresponding parts.

The letters A designate thefan-blades, which are made of any chosen formor shape, and are secured'to their shanks B in any suitable manner. Theshanks B are provided with a screw-thread, and are iitted in the socketsof a joint, C, which sockets are provided with a corresponding thread,so that the shanks B turn in their sockets, and thereby can be adjustedin any plane or angle, by which means the currents of air produced bythe rotation of the fans can be disposed in any chosen direction.: Thefans are held in the required plane by means of locking-nuts D, whichwork on the screw-shanks B, and abut against the lateral ends of thesocket-joint. By means of the screw-thread the shanks B can be movedtoward and from the socket-joint C, and thereby the fans are renderedadjustable in a 1ongitudinal direction. I can thus adapt the range ordistance of the fans to the size 0r dimensions of th room where they areput up. The fans are locked in position by means of the nut D, or by anyother means suitable for the purpose. The socket-joint C is providedwith as many lateral branches or sockets as there are fans, (of whichthere are two to each socket-joint in this example,) while it isprovided with two vertical branches, which slide on a vertical shaft,E.The branches last named are held on the vertical shaft by means ofadjustin g-screws a, and by loosening these screws the socket-joint, andwith it the fans, can be raised and lowered to the extent of the lengthof the shaft, whereby the range or position of the fans is regulated ina vertical direction. The vertical shaft E rotates in a hanger, F, whichis secured in any convenient position in the room or other place wherethe fans arc used.

In the present example I have shown two series of fans, which areconnected with each other by a band, b, running over pulleys G, whichare mounted on the respective vertical shafts, while by a secondaryYpulley and band, c, one of the shafts in connected with a driving wheelor pulley, H.

By imparting a revolving motion to the shaft of this driving-wheel H,'such motion is communicated to the vertical shafts E, and the fans areset in motion.

What I claim as new, and desire to secure by Letters Patent, is

The joint C, provided with screw-threaded sockets, in combination withthe fans A, having the screw-threaded Shanks B, the lockingnuts D,vertical shaft E, and hanger F, all being constructed and arranged tooperate substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 17th day of September, 1874.
